I want to get user activity on a web site. Using JavaScript, I can get window size and mouse position. But when I search on google, I read that it is impossible to get the window scale factor. Is this true? Why can't I get window scale?

                    Hey Kobayashi! Can you please elaborate on what you mean by "window scale" and if possible provide some screenshots explaining your definition? Thanks! – SalmonKiller Mar 12 '19 at 02:42
